Active galactic nuclei (AGNs) have been proposed as plausible sites for hosting a sizable
fraction of the binary black hole (BBH) mergers measured through gravitational waves …

The disk of an active galactic nucleus (AGN) is widely regarded as a prominent formation
channel of binary black hole (BBH) mergers that can be detected through gravitational …

We present a numerical study of relativistic Bondi-Hoyle-Lyttleton (BHL) accretion onto an
asymptotically flat black hole with synchronized hair. The hair is sourced by an ultralight …

I build a toy model in the frame of the jittering jets explosion mechanism (JJEM) of core
collapse supernovae that incorporates both the stochastically varying angular momentum …

Primordial black holes (PBHs), if they exist, may collide with and be captured by neutron
stars. We adopt a relativistic point-mass approximation to study this capture, the subsequent …

Perturber objects interacting with supermassive black hole accretion disks are often invoked
to explain observed quasiperiodic behavior in active galactic nuclei (AGN). We present …

In the absence of a sufficient amount of plasma injection into the black hole (BH)
magnetosphere, the force-free state of the magnetosphere cannot be maintained, leading to …

Supermassive black holes (SMBHs) at the centers of active galaxies are fed by accretion
disks that radiate from the infrared or optical to the X-ray bands. Several types of objects can …

Fueling and feedback couple supermassive black holes (SMBHs) to their host galaxies
across many orders of magnitude in spatial and temporal scales, making this problem …

With an X-ray stacking analysis of Lyman-break galaxies (LBGs) using the Chandra Legacy
Survey image, we investigate average supermassive black hole (SMBH) accretion …
